Langbeinite is a popular fertilizer, especially where several nutrients are needed to provide adequate plant nutrition. It has
an advantage of having K, Mg, and S all contained within a single particle, which helps provide a uniform distribution of nutrients
when it is spread in the field.
Langbeinite is totally water soluble, but is slower to dissolve than some other common K fertilizers because the particles are
denser than other K sources. Therefore, it is not suitable for dissolving and application through irrigation systems unless finely
It has a neutral pH, and does not contribute to soil acidity or alkalinity. This differs from other common sources of Mg
(such as dolomite) which will increase soil pH and from elemental S or ammonium sulfate which will lower the soil pH.
Low in chlorides, this naturally occurring mineral contains potassium, magnesium and sulfur.
